I built the Go file on a MacOS. For setting the binary to execute at a Linux OS, it was necessary to build it with the command:
env GOOS=linux GOARCH=amd64 go build hello-world.go
Run the command to print: Code.education Rocks!
docker run kalilmvp/codeeducation
The image was also built using multistage so the PROD image is really small and only executes what's necessary. Image size: 1.76MB
